title: [Age features of the allergens in allergic rhinitis patients of different age in Hubei area].
abstract: OBJECTIVE
  To investigate the distribution of positive allergens in patients with allergic rhinitis and the discrepancy among different age group.
  
  
  METHODS
  Skin prick tests were done to 2 808 allergic rhinitis patients, the major allergens of local area were tested with standard allergens. Data was analyzed with age and allergens.
  
  
  RESULTS
  Dermatophagoides pteronyssinus and dermatophagoides farinae had the highest positivity among all allergens (91.03%, 86.47%). Other important allergens were cockroach (19.55%), ragweed (15.63%) and mugwort (14.13%) subsequently. The distribution of major allergens was variable among different age group. The positivity of mold mixture I was much higher in 3-9 years old group than other age group. Positive percentage of ragweed and mugwort allergens were increased with age growing. Positive ratio of cockroach which was higher in the elder than that in the younger, was highest in 30-39 years old group. Ratio in patients with single allergen positive decreased with age growing.
  
  
  CONCLUSIONS
  House dust mite was the most important allergen of the local area, the distribution of positive allergens was variable in different age group.
